1. Effects of growth hormone in the central nervous system
ABSTRACT Growth hormone (GH) is best known for its effect stimulating tissue and somatic growth through the regulation of cell division, regeneration and proliferation. However, GH-responsive neurons are spread over the entire central nervous system, suggesting that they have important roles in the brain. The objective of the present review is to summarize a

2. Evaluation of a rat model of exercise-induced fatigue using treadmill running with progressively increasing load
Abstract: The mechanism behind exercise-induced fatigue is a significant topic in the field of sports physiology. Therefore, establishing and evaluating an acute exercise-induced fatigue animal model that explores the limits of the motor system may provide greater insight into these mechanisms. Heart rate is an important quantitative parameter that accuratel

3. In vitro embryo production in buffaloes: from the laboratory to the farm
Abstract Transvaginal follicular aspiration technique together with in vitro embryo production are the biotechnological alternatives currently available to support genetic improvement breeding programs in buffalo species. However, aspects related to animal management, lack of knowledge of the metabolic needs and biochemical peculiarities of gametes and embry

4. Morpho-physiology, yield, and water-use efficiency of Opuntia ficus-indica irrigated with saline water
ABSTRACT. Forage cactus pear is considered a xerophilic plant, so it is adapted to harsh semiarid conditions and is a forage resource of significant importance for animal production in regions that are subject to food shortage and long dry periods. We aimed to evaluate the morphometric and physiologic characteristics and water-use efficiency of ‘Gigante’

5. Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)
Abstract Distress can be defined as a biological response of an individual to long-term threats to its homeostasis and it should be avoided from an animal welfare perspective. High levels of stress hormones and the expression of abnormal behaviours are responses normally observed in distressed animals. Captive environments can provoke distress, especially wh

7. Avaliação do estresse e do desempenho de suínos na fase de creche, empregando-se técnicas de enriquecimento ambiental
RESUMO O enriquecimento ambiental é uma ferramenta importante dentro dos sistemas de produção, a fim de promover o bem-estar e favorecer a saúde dos animais. Portanto, o objetivo deste trabalho foi avaliar o efeito do enriquecimento ambiental sobre o estresse de suínos na fase de creche. Foram utilizados 32 leitões, alojados em granja experimental, dis

8. Actiflagelin, a new sperm activator isolated from Walterinnesia aegyptia venom using phenotypic screening
Abstract Background Sperm contains a wealth of cell surface receptors and ion channels that are required for most of its basic functions such as motility and acrosome reaction. Conversely, animal venoms are enriched in bioactive compounds that primarily target those ion channels and cell surface receptors. We hypothesized, therefore, that animal venoms shou

9. Digestibility, growth, blood chemistry, and enzyme activity of juvenile Oreochromis niloticus fed isocaloric diets containing animal and plant byproducts
ABSTRACT In this work, we studied the digestibility, growth, blood chemistry, and enzyme activity of Nile tilapia (Oreochromis niloticus) juveniles (0.95±0.18 g) using different animal (fish silage meal, whey meal, bovine blood meal, and red crab meal) and plant (extruded bean, extruded chickpea meal, coconut paste, Jatropha curcas meal, and chickpea meal)

11. The importance of animal studies in Exercise Science
Abstract The validity and relevance of research with animals for the development of knowledge in Exercise Science have for long been discussed. Given the complexity of the biological systems, the use of animal models offers a significant contribution to uncover new findings about acute and chronic effects of exercise, particularly when these studies in human

12. Cardio-respiratory development in bird embryos: new insights from a venerable animal model
ABSTRACT The avian embryo is a time-honored animal model for understanding vertebrate development. A key area of extensive study using bird embryos centers on developmental phenotypic plasticity of the cardio-respiratory system and how its normal development can be affected by abiotic factors such as temperature and oxygen availability. Through the investiga
